Krypton

Krypton, Kr, is an inert Nobel Gas element, found in Group 0 of the periodic table.

Atomic Number : 36
Relative Atomic Mass : 83.80

Discovery

Krypton was discovered by Ramsey and Travers in the final residues from the evaporation of liquidified air.

Occurrence

Krypton is present in the atmosphere in trace amounts (approximately 1 ppm).

Extraction

Krypton is extracted from the final residues of liquefied air by fractional distillation, from which the major components (i.e. oxygen, nitrogen, carbon dioxide, and water vapour) had been removed.

Properties

Krypton is a colourless, tasteless odourless inert gas.

Krypton is very inert chemically due to its electronic configuration.

Detection and Analysis

Krypton, Kr, is detected by spectroscopic methods.
